' I have, for the purposes 7 of illustration, shown my improved lock in connection with a chest, it will be understood I --that its use is not thus restricted sir l 6) Cedar, chests are, if the manufacturers instructions 'to keep the lid-tightly closed fol,-

" lowed, efficient, butthe average person merely closes the lid down and neglects to lock ihflS such position, thereby defeating the purpose of thech'est, becausewith the lid 'onlyipartially closed the aroma from the nside of the chest will rapidly escape, thus 1 reducing the efiiciency ofthe chest.

T he primary objectof my invention is to provide a lock of suchconstruction that the "sufficient to operate the lock to securely and tightly'hold the lid in closed position; and

- with" this andother objects in view my in- -v erition consists of (the parts and combing- 'tion of parts hereinafter pointe'd out,

From experiments made with a large nume ber oficedar chests, I havelfound that there is a leakage ofaroina ofcedarioi'l from chests through the key hole of the locks,which fof course isobjectionable, not only becausejof the escape of the aroma, but also because this escaping aroma iattacks: the exterior oils of the exterior tinishof the chests, and forms a gummy-mass which spreads rapidly andnot "only mars theappearance of the chest, but

' ,discolors any textne material thatmay come in contact with such nass.

f The primary objectofmy invention is to provide a lockfor cedar chests of such con- 7 j sjtruction to prevent the leakage of the aroma of cedar oiltherethrough to the exterior of I Q- the chest. 1' V 'A-further. object efmyjihx ention is;to pro- I v d uc a ck Withew bin d k y end perat ngip he bylth le k' a c im y ut I matically Ymove to locking position ands rea nmoved'from suchpositionfby moVingthe-said fcombin'ed pin, and with these and'otherob- :1 jects in view. my invention? consists of the parts a'nd combination of. parts hereinafter pointed out-T T Inthedrawingsi ,g p ;Figure{ 1 aifron elevation-of vnl yal elevation.

proved lock with the casingplate removed The reference numeral 1 designates the stem, the

plate of the lock whichhas a flange 2 at its upper edge, provided with aca'tch hole 3.

A casing dis attached to said plate and consists ofv a wall of the desired height, which walliis provided on one side Withrecesses or notches 5 and 6, and on the opposite side with stepped recesses o'r notches 7 and 8;

V A pin 9'is secured to the plate 1 within the casingon whichisfix'edly'secured a flat spring 10, the end portions 11. and 12 of which are deflected away fromftheplate 1. On this 9, and above the spring 10 is secured a coiled spring, the end 13 of which bears against the wall 4 of ,the casing, while the :other end '14 extends, substantially, transverse of the casing and terminates in the pinlike end l5, whichextends at right angles to the plate 1. f f 1 The keeper 16 is provided with an opening 17 which is of greaterdiameter than, and is adapted to receive the pin .9, the said greater diameter permitting the keeper to be tilted bodily with reference to the post, for the purpose hereinafter pointed out. Keeper l6is provided: withlugs18,19, 20 and 21 extending ,laterallythrefroin, which lugs are, when the parts are assembled, seated in the recesses'5,

6,7 and 8, respectively, the lugs 19 and 21 functioning aspivots for the keeper 16 on which the keeper is tilted. ,The keeper 16 is QPI'OYld GC l with a lug or finger22, which is in constant engagement with the end 12 of the T spring 10, whereby the keeper ismaintained constantly; in locking position. The coinbined key and keeper operating pin 23 is rigidly attachedto thev keeper and at its base the keeper is, preferably, dished to form a seat or pocket in .which'a coiled spring 24 is seated, 5 Thekeeper is also provided with an q opening therethrough into which the pin 15 [of the spring arm 14L- projects. A latch ope11- ing 25. is formed through the keeper near its ropede a Sui-mounting the keeper 16 is locking bolt j 26 torzthe keeper, said bolt having notches or recesses 27 and'28 to receive the pin of the spring arm 14.

Thisbolt slides *in notches formed injthe edge of the casing wall 4 and is. pro,-
